Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The embodiment of the present invention provides a method for PON system link loopback detection, such as figure 1 As shown, the method includes the following steps:

[0036] Step 101, open the network management interface, set the detection parameters of the loopback link, enable the loopback detection function of the core switching disk, and send a first-level detection message to each uplink port and the slot port of each service disk through the core switching disk .

[0037] It should be noted that the Ethernet type in the first-level detection message is set by the user, for example, the Ethernet type can be set as Oxeffa.

[0038] Step 102 , the core switching disk judges whether a first-level detection message returned by other uplink ports or slot ports is received within a preset time, if yes, execute step 104 ; otherwise, ...

Abstract

The invention discloses a method and a device for loopback detection of a PON system link. The loopback detection function of the core switching disk is turned on, and a first-level detection message is sent to each uplink port and the slot port of each service disk respectively; if not received If there is a returned first-level detection message, the detection is ended; otherwise, it is determined that there is a loopback in the PON system; if there is a loopback between the uplink port and the uplink port, the detection is ended; if there is a loopback between the uplink port and the slot port or If there is a loopback between the ports of each slot, the loopback detection function of the service board is enabled, and each service board sends a secondary detection message to the designated ONU. If each service board does not receive the returned secondary detection Otherwise, according to the ONU authorization number carried in the secondary detection message and the slot number of the service board, the service board and the specified ONU that generate the loopback are precisely located. The invention has a simple implementation process, can report the detection result in time, and greatly improves the efficiency of the PON system link loopback detection.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for loopback detection of a PON system link. Background technique [0002] With the development of communication technology, users who access broadband are becoming more and more common. The broadband access device is connected to the transmission and convergence layer equipment on the network side, and the user side is connected to the user's home gateway or DSL (Digital Subscriber Line, Digital Subscriber Line) modem. The diversity and complexity of user access causes link loopbacks. For example, users often encounter problems such as being unable to access the Internet or make calls. Most of these problems are due to the loopback in the link of the system. The packets coming in from the uplink port go back to the device in some way after leaving the optical line terminal, such as in PON (Passive Optical Network, Passive Optical Network). ) device, ...
